A staircase rail
f(x)=x-1
D: (negative infinity, infinity)
R: (negative infinity, infinity)
No discontinuities.
The function is symmetric about the origin,which means it is an odd function.
f(-x)= (-x)-1= -x-1 odd
The limit as x approaches infinity is infinity.
The limit as x approaches negative infinity is negative infinity.
